The aim. To reduce the incidence of perinatal pathology in women who have used various methods of contraception, based on the study of the functional state of the fetoplacental complex (FPS), as well as improving diagnostic measures and tactics of pregnancy.Materials and methods. 140 pregnant women were studied with their division into control and 3 test groups depending on the method of contraception in the anamnesis, using clinical, laboratory and instrumental research methods during pregnancy and childbirth.Results. The study found that women with a history of intrauterine contraception (IUC), in contrast to combined oral contraception (COC) and combined oral contraception containing folate (COC+F), had a higher incidence of complications during pregnancy and childbirth, as well as fewer newborns with a satisfactory condition at birth. Assessment of folic acid levels at 6-8 weeks of gestation showed significantly better results among women with a history of COC+F, compared with IUC and COC. In the group of women with IUC in the anamnesis, significantly worse mean endocrinological values prevailed, and there was also a greater number of pregnant women with disorders of fetal-placental blood flow. More pronounced dystrophic changes in the placentas of women in this group were pathomorphologically confirmed.Conclusions. The presence in the anamnesis of IUC is accompanied by a high proportion of pregnant women with various pathological conditions and is a risk factor for FPS dysfunction. The use of COC+F in the anamnesis is the best option for women of different risk groups.
